Highly sensitive and selective chemosensor for Cu 2+ and H 2 PO 4 − based on coumarin fluorophore

A colorimetric and ratiometric fluorescent sensor for sequentially detecting Cu2+ and arginine based on a coumarin–rhodamine B derivative and its application for bioimaging

“…[12][13][14] However, most of them are based on "turn-off" changes in uorescence intensity because Cu 2+ is usually used as a uorescent quencher via an energy or electron-transfer mechanism. [15][16][17][18] Therefore, the sensitive "turn-on" uorescent sensors to monitor and visualize Cu 2+ are highly demanded.…”

TiO2 nanotube arrays decorated with Au and Bi2S3 nanoparticles for efficient Fe3+ ions detection and dye photocatalytic degradation

“…Recently, heavy attention to environmental protection and human health has urged active research on the underlying effects of transition metal ions. Therefore, scientists have made tremendous efforts to synthesize effective sensors for detecting transition metal ion [55][56][57][58][59][60][61][62] . In our sensing experiment, the sample was immersed in solutions (10 and Zn 2+ ) for 1 hour to study the selectivity of the sample to metal ions.…”

An Acylhydrazone-Based Fluorescent Sensor for Sequential Recognition of Al3+ and H2PO4−

“…While numerous fluorescent chemosensors for a single analyte have been reported, fluorescent chemosensors that allow the sequential sensing of multiple analytes with great selectivity and sensitivity are still needed [19][20][21] because they are more cost-effective, recyclable and practical [22][23][24]. Several fluorescent sensors have been addressed for consecutive sensing of Al 3+ and several anions [25][26][27][28] or several cations and H 2 PO 4 − [29][30][31]. In addition, Kumar et al reported a fluorescent sensor for sequential sensing of Al 3+ and H 2 PO 4 − /HSO 4 − [32].…”
